Regardless of whether you are threading a new material or repairing a damaged thread, there are several factors to consider as well as procedures to follow to ensure that you are able to produce the best job, with the least amount of breakage in your tools.
Learning More about Threading, Taps, and Dies
Before you begin, it is important to note that there are actually two types of threading, external and internal. Internal threading is performed using a tap in a hole that is drilled to a specific diameter intended for the thread size as well as a pitch that you want to cut. External threading, on the other hand, is performed using a tool called die. This is applied to a specific diameter of rod for the pitch and size of the thread that you want to cut. Both tap and die tools can be used to cut new threads and repair damaged ones.
The threads produced using dies and taps, by hand or machine, are known as cut threads. They are generally of better quality and exceptional tolerance.
Taps come in three basic configurations. These are the taper, bottoming, and the plug. Taper taps come with seven to ten threads at the tip. This type enables easy starting of the threads in a hole. This is often referred to as a starter tap. This tool can be used to start the thread in the hole for another tap to finish. Bottoming taps, on the other hand, does not have any ground threads at the starting end. They are generally utilized after a taper or a plug tap. Plug taps are just like taper taps. They have threads at the starting end of the tape. However, the threads are fewer.
Prepare the Materials and Tools
When tapping threads (Internal threading) using a drill, you have to prepare the materials and tools that you will use beforehand. In addition, it is important to note that for taps to cut, they must be harder than the actual materials that they are cutting. With this additional feature, the taps are easily broken as they are brittle. Thus, you should always handle taps with care. You should also make sure that the tap is properly secured on the drill before tapping any material. You have to familiarize with the right buttons to operate the drill to avoid any accidents or mistakes.
Don’t Forget the Lubrication
Once you have everything ready and set up, you can start to lubricate the material you are working on. Lubrication will reduce friction binding. In addition, this will also aid in chip removal. You can lubricate the material using a tapping fluid, a machine oil or even WD-40. There is no need to use a lot of lubrication. You can use a little lubrication to make the job easier.
Take Your Time
You do not really want to mess up a tapping job. Thus, you have to take your time. You have to be careful when performing a tapping job. You have to go slow. It is ideal that you start slow without applying too much pressure on the drill while it is working on the material. Moreover, you should not go all the way through. You have to make sure that you are paying close attention to what you are working on.
